With some development boards, low power usage is an afterthought. Especially when price and usability is the main selling point. So what should you do when it's time to turn around and make that project of yours run on a battery or...

A button is a button, and an LED is a LED, but this LED illuminated button is a lovely combination of both! It's a medium sized button, large enough to press easily but not too big that it gets in the way of your project panel. It has a...

Remember those cereal commercials that would always say, "part of a complete breakfast"? Well the Pi Zero's a lot like that bowl of cereal - while it's great on its own, you need a lot of accessories to make it a complete meal. The Pi...

Is this not the cutest, little display for the Raspberry Pi? It features a 3.5" display with 480x320 16-bit color pixels and a resistive touch overlay just like Adafruit's popular original, but this one is engineered specifically to work...

One of each of our favorite 13.56MHz RFID/NFC Classic 1K tags - 5 in total! Credit card size 1" diameter 'laundry' clear tag 1" diameter 'laundry' white tag Key fob Sticker These can be read by almost any 13.56MHz RFID/NFC reader but...

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference, as well as calculations to handle any non-linearities. For a long time Adafruit have MAX31855K breakout, which works great but is only for...

Your microcontroller probably has an ADC (analog -> digital converter) but does it have a DAC (digital -> analog converter)??? Now it can! This breakout board features the easy-to-use MCP4725 12-bit DAC. Control it via I2C and send it...

Breathe easy - we finally have an I2C VOC/eCO2 sensor in the Adafruit shop! Add air quality monitoring to your project and with an Adafruit CCS811 Air Quality Sensor Breakout . This sensor from AMS is a gas sensor that can detect a wide...

This breakout board will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can just use the handy INA219B chip on this breakout to both measure both the high side voltage and DC current draw over...

Need to add analog inputs? This chip will add 8 channels of 10-bit analog input to your microcontroller or microcomputer project. It's super easy to use, and uses SPI so only 4 pins are required. We chose this chip as a great...

The Adafruit Feather nRF52 Pro is our latest Bluetooth Low Energy board for advanced projects and users who want to use a fully open source Bluetooth Low Energy 5.0 stack . It has a native-bluetooth chip, the nRF52832, as well as built...
